Which is the Biggest of the Gas Giants in our Solar System?
Jupiter
100
Why do Jovian planets have a low density?
Because they are composed of mainly gases.
100
Which planet has the shortest days?
Jupiter with 10 hours
100
Name a therory of how the jovian planets formed.
Nebular, Proto-Planet
100
Name three properties of the gas giant moons.
Spherical, made up of rock and metals, and have volcanic activity.
200
Which of the Jovian planets has the smallest mass?
Uranus
200
No they have a hard core
Are the Gas Giants entirely made up of Gas?
200
What is the tilt of the Gas Giants?
7 degrees
200
Who discovered Uranus? What year was it discovered?
Uranus was discovered by William Herschel in 1781.
200
How thick are the rings of the planets?
1 meter or 3 feet
300
How many times can earth fit into Jupiter?
318
300
Which of the jovian planets has the lowest density?
Uranus
300
What is the planet with the longest days?
Neptune
300
How is the proto-planet hypothesis similar to the Nebular hypothesis?
They both involve a nebulae collapsing.
300
why are Io and Europa huge topics of interest?
Because they have the most volcanic activity.
400
Which planet is the 3rd largest in diameter?
Neptune
400
What are the Gas Giant planets mostly made up of?
Helium and Hydrogen
400
The more rotation causes this to happen to gas giant planets poles?
It flattens them
400
Explain why we cannot specify who discovered Saturn or Jupiter?
Because they were both very visible to many people throughout nightime, many people were able to witness the two planets. No one is quite sure who was first to discover them.
400
The moons of the gas planets are like rocky or terrestrial planets because of this:
On the moons of gas giant planets ice forms further from the sun.
500
What is Saturn's mass?
94M
500
Scientists refer to the Jovian planets as to having a rocky core, why is this misleading?
because they are mainly composed of liquid compounds and molten metals.
500
Suppose you were a hundred pounds and you traveled to Jupiter, how much would you weigh?
236 lbs
500
Explain the Nebular hypothesis.
The Nebular hypothesis involves a nebulae being pulled by gravity, which causes it to collapse into a flat, rolling disc. Over time the nebulae merges into the planets.
500
How are the rings of the planets created?
A small moon collides with another moon thats particles then gets into the orbit.
